Open source digital sampling oscilloscope

January 7, 2010 in logic analyzer | 3 comments

Please join us in the forum to discuss a digital sampling oscilloscope add-on for the open source logic analyzer (currently referred to as project SUMP PUMP). Our general goal is to design an inexpensive expansion board that samples analog voltages at 50MHz+.

The combination of a logic analyzer and sampling oscilloscope is a powerful debugging tool. The logic analyzer displays changes in signal states, the oscilloscope reveals how clean the transitions are.

We’re in the process of choosing a parallel ADC chip and discussing analog front-end designs. Feel free to make requests, suggestions, or just follow along.

    I knew this would happen… I’ve just ordered a DSO off ebay, now there’s gonna be a far cheaper alternative.

    How far away is the Sump Pump from a release by the way? Have you decided on the name yet?

    The PCBs for the SUMP PUMP shipped on the 28th of December, but the postal slow-down out of China over the holiday is making them take forever to get here. I hope there here really soon, or I’ll try to have another batch made locally.

    We’ll hold off on the name until we build the first prototype.
